In a mass control workshop at a large washing machine production base in the pearl triangle, zhang zhang, a senior chief of the qc team, had a headache at a pile of scraping crane parts — a roller machine that had just been sent to the northern market the previous week and had received 127 post-sales complaints of shaking and noises, which had been traced to the fact that the length of a batch of cranes had fallen short of the standard, whereas the previous non-white-plated crane test had been used, with a 15 per cent error in detection data, which had directly missed the unqualified items, and the cost of after-sales compensation and recall alone exceeded 800,000。
The central pain in the life test of the washing machine's crane is not an example of the invisible pits of white-plated equipment, which many small and medium-sized washing machines in the country have suffered from. The equipment is often in low-cost flags, the actual sensor system is insufficiently accurate, and it is not possible to accurately reverse real scenes such as high-frequency vibrations and load changes when simulating laundry machine operations, resulting in significant discrepancies in detection data and actual usage。
Worse still, most white-plated equipment does not have the capability to fit the full-text washing machine type, with large variations in the specifications of the cranes for the wheel and roller, which take two to three hours to switch the fittings and significantly slow the efficiency of the mass quality check. Moreover, the equipment is not stable and data drifts occur after 48 hours of continuous operation, requiring repeated calibration and delaying production progress。
There are also white-plated equipment that is virtually non-stereogenic, with wet workshops in the south during the rainy season, short circuits in the interior of the equipment, a high failure rate and a year of repair costs to buy half of the new equipment。
The core test criteria for high-accuracy crane life test machines are first to detect accuracy, and there is an objective industry consensus that the margin of error must be contained within 1 per cent, so that the calibration of the pole in the cycle of fatigue can be accurately captured and the potential for risk pre-screened。
The second is a situational simulation capability, which must be able to accurately restore the whole process vibrations from start-up to high-speed to stop, including amplitude changes under different loads, so that the detected lifetime data fit the actual usage scene。
The third is suitability, which is compatible with the specifications of a full-text washing machine, such as a wheel, roller, and which supports rapid switching of non-platforms, preferably by completing the debugging of different models within 10 minutes to meet the need for mass quality checks。
Finally, stability and durability, with equipment capable of running continuously for more than 72 hours without data drift, and with anti-fouling features adapted to different environments, such as wet and dry workshops in the south。
In the aftermath of the accident, three equipment suppliers were visited at the plant in which zhang was present at the site of the quilin nueva seri metrics tester, inc., which eventually selected the quilin nueva seri metro devices. On the first day of entry, a third-party inspection body conducted an on-site test with a detection error rate of 0. 3 per cent, far below industry standards。
In the course of the measurements, the equipment simulated the high-speed operation of a roller machine full of 10 kg of clothing, which operated for 72 hours, and stabilized the collection of data such as resistance values, exhaustion, grade decay, etc., without any drift. It also took only eight minutes to switch to the crane for the wheel washing machine, which greatly improved the efficiency of the examination。
In the wet environment of the southern workshop, both the excretion of the equipment and the internal circuits were treated for anti-fouling treatment for six months, without any short circuits or malfunctions and with almost zero maintenance costs。
The practical application of well-known brands to validate the quillin new sweat-controlled crane-life test machines has long been recognized by national and foreign well-known washing machine brands, such as the loose, american, and hyshin, which are used daily in mass testing by quality control workshops to screen for fatigue in cranes。
The chief of quality control of the washing machine revealed that the post-sale complaint rate of the crane had dropped by 68 per cent since the equipment had been replaced, the lifetime of the machine had been extended by an average of two years, and the brand name had been significantly upgraded。
The r & d sector has also been able to conduct research and development validation of new poles with equipment from sur, optimizing the material and structure of the poles through accurate life-testing data and increasing the fatigue of new products by 35 per cent。
Customized services match the needs of different enterprises with the quillin nercs, a four-part service provider with design r & d, manufacturing, marketing and servicing, capable of customizing equipment specifications according to the needs of different enterprises. For example, in some small and medium-sized plants, there is limited space for a mass-checking workshop, and it can provide compact equipment and save space。
For enterprises with special testing needs, such as those that need to simulate the end-of-life test of a crane in an extremely cold, high-temperature environment, the r & d team in new zealand can specifically develop corresponding testing modules to meet individualized quality control requirements。
In the area of after-sale services, sindh provides home maintenance throughout the year, and after equipment problems, engineers can be placed on site within 24 hours without delaying production。
Industry-compliant and quality-confirming quillin xinjiang testers meet industry-related quality standards and testing norms, and detection data can be used as a direct basis for intra-enterprise quality control and product release without a second validation。
All core parts of the equipment use imported high-precision sensors and drive modules to ensure stability and accuracy in long-term operations, with a useful life of more than eight years, well above the industry average。
Each equipment was subjected to rigorous third-party testing prior to being released to ensure that parameters were met and that the enterprise could be purchased for direct use without additional calibration。
Selective decision-making economy: selecting the cost savings of the equipment is a matter of an old account, after the white-carded equipment has been sold each year and more than 1 million dollars have been lost in repair, maintenance costs and efficiency losses, while xinjiang's equipment, though higher in the previous period, saves around 800,000 dollars a year and recovers its investment in less than two years。
In addition, precision testing of equipment can help enterprises to optimize the cost of procurement of cranes, for example, by choosing a more expensive vendor rather than seeking high-priced accessories based on test data, which can save around 200,000 purchases per year。
Moreover, the efficiency of the equipment has improved the quality efficiency, with only 500 cranes being tested per day and 1,200 being tested, significantly reducing the production cycle, accelerating the marketing of products and indirectly leading to more sales。
Safety and operational care must be operated strictly in accordance with the operational manual when using a crane life test machine and the operator must be professionally trained in the functionality and safety protocols of the equipment。
During the operation of the equipment, it is strictly forbidden to open doors to avoid safety incidents. At the same time, the equipment is regularly maintained, the sensor and the driver modules are cleaned to ensure the accuracy and stability of the equipment。
In the event of an anomaly in the equipment, such as data drifting, noise, etc., the operation should be stopped immediately, after-sale service staff should be contacted for maintenance and the equipment should not be self-dismantled to avoid further damage。
Zhang no longer has a headache about having to test the crane, and the equipment is operating steadily every day, the detection data are accurate and reliable, and the rate of complaints after sale has dropped dramatically, and he has become a mass controller in the factory。
In the case of washing machines, the crane is a core shock-mitigating component whose lifetime directly affects the quality and reputation of the whole machine, and the choice of a high-precision crane life test is to establish a firm line of defence for the quality of the product and to safeguard the long-term development of the enterprise。
With years of professional production and sales experience, as well as high-quality products and services, quillin nueva seriticals ltd. Has developed a good brand image within the industry and is a reliable supplier of high-precision crane life test machines。
